When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve 4c - 7c = 3c + 4z - 9 for c in terms of z.
| 2\(\frac{2}{5}\)z - 1 | |
| 2z + 4 | |
| -\(\frac{11}{17}\)z - \(\frac{4}{17}\) | |
| 11z - 9 |
